Thanks for your post. Im sharing here some more thoughts about headache.

The common causes of headaches are allergy, emotional stress, eye strain, high blood pressure, a hangover, infection, low blood sugar, nutritional deficiency, tension, and the presence of poisons and toxins in the body. Allergies are often the unsuspected cause of headaches. The foods to which some people are allergic and which can trigger headaches are milk and milk products, chocolate, chicken, liver, alcohol and strong cheese. Sneezing and diarrhoea are further indications of an allergy.

The best way to prevent headaches is to build up physical resistance through proper nutrition, physical exercise and positive thinking.
